Now. I can note that Volume 190 Number 1 of Molecular and Biochemical Parasitology also illustrates a phylogenetic network. Hopefully, the widespread nature of these three journals reflects an increasing recognition of the importance of networks in phylogenetics.

The illustration is from the paper by Eva Tydén, Annie Engström, David Morrison and Johan Höglund: Sequencing of the β-tubulin genes in the ascarid nematodes Parascaris equorum and Ascaridia galli, on pages 38-43.
